Gaussian Processes for Glitch-robust Gravitational-wave Astronomy

Understand

Interferometric gravitational-wave observatories have opened a new era in astronomy.

• The rich data produced by an international network enables detailed analysis of the curved space-time around black holes.
• With nearly one hundred signals observed so far and thousands expected in the next decade, their population properties enable insights into stellar evolution and the expansion of our Universe.
• However, the detectors are afflicted by transient noise artefacts known as "glitches" which contaminate the signals and bias inferences.
